Any thoughts on this holding up outdoors being used as a debris sled?

TRANR's 1/4" 40" x 8' Rubber Mats can be used outdoors and can be used as a debris sled. Rubber is very resistant to the elements and is mold and mildew resistant. These rubber mats are also very slip-resistant, and more so when wet. The only thing you will notice is that the mats will fade a bit in direct sunlight.
